Dorzolamide/timolol fixed combination effective for normal-tension glaucoma

Researchers have found dorzolamide/timolol fixed combination to be an effective IOP-lowering agent for patients with normal-tension glaucoma.A prospective, open-label, multicenter study included 37 patients with treatment-naïve, normal-tension glaucoma who received dorzolamide/timolol fixed combination therapy for 12 weeks to reduce IOP. For each visit, the researchers measured patients’ IOP at 9 a.m. prior to the administration of dorzolamide/timolol fixed combination therapy; IOP was then measured again at 11 a.m. and 5 p.m. IOP was also measured at 1 p.m. and 3 p.m. at the 12-week follow-up.
